Everything that you could guess about BISON B.C.'s music from their name is probably true. It can shift a plodding stomp into a breakneck stampede with shocking agility, it's well versed in stone age metal (although the "b.c." likely stands for the band's home, British Columbia) and it thrives on a whole lot of grass. Not that they sound retro on Dark Ages, their second record for Metal Blade. It's too heavy for the days of HAWKWIND, too fast for their doom metal peers and too complicated to sound like any of the leaders of the '90s stoner metal boom. It also confirms that for whatever subgenre they get pigeonholed as, BISON B.C are one of the best.
